First I have a little tidbit of info to add. I found several estimates of the Wiimote FOV on the Web but attempting to debug down some tracking problems, I manually measured the FOV and came up with these values.Horizontal FOV = 41.36462 degreesVertical FOV = 31.67174 degrees

which are pretty close to others' measurements but work out more precisely for my application.

Now for my question. Has anybody computed out how much radial distortion the Wiimote camera has? I am having some computational errors and I need to rule out the camera optics as the culprit. Just seeing if the info is already out there before I start the grueling process of measurement. Thanks.
